Hmmm... I tried to attach the summary reports for the three machines (similar to the partial-so-far one for the pi0w) but no matter what I try it says I have an invalid file extension ???

I searched for the message "invalid file extension" and learned from here

viewtopic.php?f=66&t=308049&hilit=Inval ... n#p1843264 that zip files are OK. And that's it? So instead I'm putting the frequency/temperature/throttling summary reports that I had intended to attach, between code tags instead.

I was doing these compiles both just to see if it could be done, and as stress tests for the different pi's (gcc_compile is clearly an excellent stress test). I appreciate the generous suggestions as to how I might recover the failed compiles, but that may be more work than I'm up for.

Here are the summaries as to temperature, arm_frequency, and throttling status, for each of the machines, the data having been noted once a minute for the duration of the run (or longer, if I didn't notice exactly when they finished). The pib(256) and pi0w compiles are still running, the pi2, pi3a+ and pi3b failed, and the two different pi4s finished successfully. These were run at different times so there may be some differences in what's reported on or how its presented. There's a gap of 320 minutes on the pib where the compile was still running but I wasn't producing the data, but I don't think anything different happened during that time, the pib is the poster child for slow and steady... See the comment at the beginning of each section.
